This is what team 422 learned. Build a complex and ultimately failing robot in 2008, then build a ridiculously simple robot and win 2009 Quality Award and become 2010 Regional Finalists. Simplicity is the best design strategy, even in real life engineering.

Do the lights fade in and out upon teleop initialization? Does it make the oh so awesome TARDIS sound? :yikes:

I wish it made that sound. -Nick |

Beautiful robot 1503! I see big things for you!

It takes a lot more force to do so with these flanged lightening holes. These punches made the difference between having to swiss cheese a super heavy over-trussed frame and being 15 lbs underweight. -Nick |

If not for the mini-flanges, would the sidewalls be just bare sheet? If so, that would explain why the mini-flanges help so much. |

All the pieces do have folds in them though. Here is a photo of one of our practice bot siderails being made. Here is a closeup of that siderail. After the first successful rail, we switched to an impact wrench to make things go faster. Also, our bearings holes are punched in the same way. It's really neat, come take a close look at our robot sometime. -Nick |

Holy reduction batman! Is that a rs755 mated to a cimulator mated to a gem 3 stage planetary connected to at least a 3:1 chain reduction? When i come up with solutions like this my team makes me sit in the corner. This year i had to power our arm with two rs755 mated with cimulator and a tough box plus 3:1 chain reduction to make up for the lack of gearing.

It works surprisingly well, but one thing we've discovered is that the GEM won't backdrive (the radial load from the gear it drives causes the output shaft to bind inside somewhere), so we use a big wrench when we need to move the arm without power. |

Personally, after spectating at FLR, I'm still inclined to believe that we can be sufficiently effective without. |
